If re-inserting missing blocks back into the IPFS/GNUnet/whatever is made optional and is off by default, then=C2=A0almost nobody will enable th= e =E2=80=98caching peer=E2=80=99 option and we will have freeloaders, somewha= t defeating the point of GNUnet/whatever. In a classic setting (=E2=80=98plain old HTTP=E2=80=99), serving and downlo= ading is a separate thing. But in a P2P setting, downloading cannot be separated from uploading -- strictly speaking, a peer might be able to download without uploading (depending on the P2P system), but that's anti- social, not something that should be done by default. However, if re-inserting missing blocks is _on_ by default, then there doesn't seem to be any trouble.
